About this project
NewRange Copper Nickel, LLC (NewRange), formerly known as PolyMet Mining Corp. (PolyMet), is proposing changes to its NorthMet Project, a mine and associated processing facility for the extraction of copper, nickel and platinum group metals. Because these proposed changes differ from what was evaluated in the project’s 2016 Final Environmental Impact Statement (EIS), the DNR is preparing a Supplemental EIS (SEIS).
NewRange is proposing several modifications to the NorthMet Project design that was previously reviewed. They propose to adjust the layout of the mining and processing areas and remove an additional processing step that had been part of the previous design. Daily ore production would increase from approximately 32,000 to 40,000 tons, while the mine’s lifespan would decrease from 20 years to 16 years. Instead of rail, the company proposes using a conveyor system to move material from the mine site to the on-site processing plant. The company also proposes a new approach for managing tailings; rather than using the site’s existing tailings basin for tailings disposal, the new design proposes in-pit tailings disposal..… DETAILS FORTHCOMING.

The SEIS will examine the potential environmental effects of the proposed changes and provide updated information for public review and regulatory decision‑making. In addition NewRange may be required to obtain new or amended permits and other approvals from state, federal and local agencies before construction and operation. Final decisions about any required state or local permits cannot be made until the SEIS is deemed adequate.
